Suppose a firm purchases capital and labor in competitive markets at prices of r=6 and w=8, respectively. With the firm's current input mix, the marginal product of capital is 7 and the marginal product of labor is 10. Is this firm minimizing its costs? If so, explain how you know. If not, explain what the firm ought to do

can you please explain in detail

3. a) Suppose that a firm has a capital cost (r) of $8 and a labor cost (w) of $4. Graph an isocost line associated with spending $1,000. On the same graph, draw another isocost line associated with spending $2,000. What are the slopes of these lines? b) Using our cost-minimizing (economic efficiency) condition, what is the optimal ratio of the marginal product of labor to the marginal product of capital for this firm? Why? Use a production isoquant on...

A firm uses skilled labor, unskilled labor, and capital, and is initially in equilibrium. Suppose that the wage paid to unskilled labor falls, and that unskilled labor is a substitute in production with both skilled labor and capital. Depict in separate graphs of (a) capital and unskilled labor and (b) capital and skilled labor how the original equilibrium choices change in response to the decline in wages paid to unskilled workers. What are the expected impacts on the wage and...

A firm manufactures at home, and faces input prices for labor and capital produces q units of output using L units of labor and K units of capital. Abroad, the wage and cost of capital are half as much as at home. If the firm manufactures abroad, will it change the amount of labor and capital it uses to produce q? What happens to its cost of producing quantity q? The manager would also like you to explain the Cobb...

Suppose a firm has a labor demand curve given by w = 20 - 0.01E. Furthermore, suppose that the union representing workers in the firm derives utility from the wage rate and the level of employment according to the utility function U = w · E where the marginal utility of an increase in the wage is MUw = E and the marginal utility of an increase in employment is MUE =w. (a) Graphically depict the union's utility-maximization problem, as...

   Suppose we have a competitive labor market. What is the marginal benefit to the firm of hiring another worker? Explain why. What is the marginal cost to the firm of hiring another worker? How does the firm decide how many workers to hire in the short run? In the long run, capital is no longer fixed Explain how this changes the labor decision for the firm. What is the main difference between labor demand in the short run and...

Why do we, as consumers, prefer the prices found in competitive markets? How are the prices in perfectly competitive markets determined? Explain, Which of the four market structures that we covered is most profitable for the firm? Is this the best market structure for consumers? Why or why not? Explain. We've made a pretty big deal about the differences between fixed and variable costs. Why does variable cost change as output changes? From your perspective as a manager, why is...
